我有一个pinescript需要从版本2转换到版本4

Question

这是版本2的原始代码，但转换后的结果与版本2完全不同。在转换为版本4时，我会犯任何错误

//@version=2

// Pull traditional HLC candle values
pHigh = security(tickerid, pivotTimeFrame, high)
pLow = security(tickerid, pivotTimeFrame, low)
pClose = security(tickerid, pivotTimeFrame, close)

// Calculate pivot points
pp  = (pHigh + pLow + pClose ) / 3.0

// First level
r1 = pivotType ? pp + ((pHigh-pLow) * 0.382) : (2 * pp) - pLow

// Second level
r2 = pivotType ? pp + ((pHigh-pLow) * 0.618) : pp + (pHigh - pLow)

// Plot pivots

Answer 1

这是因为由于pine v.3安全性具有参数lookahead，默认情况下为false。为了使安全行为像第3版一样，您应该将该参数设置为true：

security(syminfo.tickerid, pivotTimeFrame, high, lookahead=true)

但是我要警告您，使用lookahead=true会展望未来，并且可能会影响研究/策略的准确性。
